7 ∣ 4 x - 2 ∣ = 21

x = - \frac{1}{4} or x = \frac{5}{4}

Decimal Notation

x = - 0.25, x = 1.25

Solution steps

7 ∣ 4 x - 2 ∣ = 21

Divide both sides by

7

∣ 4 x - 2 ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

4 x - 2 = - 3 or 4 x - 2 = 3

4 x - 2 = - 3 or 4 x - 2 = 3

x = - \frac{1}{4} or x = \frac{5}{4}

0 = ∣ p + 8 ∣

3 ∣ x + 14 ∣ = 6 x + 33

- 3 ∣ 7 x ∣ = - 42

- 5 ∣ u ∣ = - 17

∣ x ∣ - 2 = 21
